This broke when path changed. It's a bit
weird to run the cephfs tests by default
now that vstart_runner is not cephfs-specific,
but for the moment just restore the old
behaviour.

This commit amends the MDS thrasher task to also work on multimds
clusters. Main changes:
o New FSStatus class in tasks/cephfs/filesystem.py which gets a snapshot
of the fsmap (`ceph fs dump`). This allows consecutive operations on
the same fsmap without repeated fs dumps.
o Only one MDSThrasher is started for each file system.
o The MDSThrasher operates on ranks instead of names (and groups of
standbys following the initial active).
o The MDSThrasher also will change the max_mds for the cluster to a new
value [1, current) or (current, starting max_mds]. When reduced,
randomly selected MDSs other than rank 0 will be deactivated to reach
the new max_mds. The likelihood of changing max_mds in a given cycle of
the MDSThrasher is set by the "thrash_max_mds" config.
o The MDSThrasher prints out stats on completion, e.g. number of
mds deactivated or mds_max changed.

Don't construct Filesystem and MDSCluster if there
are no MDSs in the system, don't construct MgrCluster
if there are no mgrs in the system.

We can't atomically append to two env backends, which means
that we can see size mismatches when we inject failures.

Some of these tests to fork and assertion tests that leave
core behind, and that is normal. Disable core dumps.

A more generic CephTestCase and CephCluster, for
writeing non-cephfs test cases.
This avoids overloading one class with the functionality
needed by lots of different subsystems.

The branches got mixed up and the merged one wasn't
the same one that was tested. This is the one that
works!

mon_seesaw task replaces a monitor with a newly reployed one, in a
single-mon test including this task OSDs will not be able to connect
to cluster if the tracker#17558 is not fixed on the monitor side.

This was only used in this task, and it is much too
ceph-specific to belong in teuthology.
